Curved surface area of a hemisphere refers to the area of the outer dome minus the base. The formula for CSA is: Curved Surface Area = 2πr2. The total surface area of a hemisphere covers the curved surface and the flat base. The formula for TSA is: Total Surface Area = 3πr2. Learn the surface area of a hemisphere—curved and total—with stepwise formulas, clear examples, and smart tips for faster calculations. Perfect for board exams and quick revision. A hemisphere is a three-dimensional shape with the following properties. Formed by dividing a sphere into two halves along its diameter. Each hemisphere consists of a curved surface and a flat circular base. This shape is commonly seen in everyday life, such as when cutting a cherry in half or dividing the Earth into the Northern and Southern Hemispheres. Hemispheres can be either solid, like a half-filled bowl, or hollow, like the top half of a spherical container. Properties of Hemisphere ... Curved surface area of the hemisphere formula is defined as the area covered by its curved surface. It is equal to half of the total surface area of a sphere. The formula for the curved surface area of the hemisphere equals two times the product of pi and the square of the radius of the hemisphere. where,
